Vampire Male, Biting Human Female.

I want you to image this. This involves not only thirst but possibly love.
The Vampire boy and Human girl have been explaining an event. They look into each other's eyes and the Boy's thirst suddenly grows. They still look into each other's eyes until he slowly bites into her neck. He is hugging her tight each minute. The girl is clenching her hands and she closely closes her eyes shut tight.
